Can't get $(date +%F) set as environment variable
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}

I would like to create an environment variable that will output the current date. I have added the following to ~/.pam_environment:
TODAY=$(date +%F)
Apparently, you have to log out after changing ~/.pam_environment. I did that but
echo $TODAY
outputs a blank line.
What am I doing wrong?

~/.pam_environment is not a script file. Use ~/.profile instead:
export TODAY=$(date +%F)

You forgot the "quotes" Here is a Cool Link for more examples.
TODAY= date +"%F"

Unfortunately that did not work. I tried experimenting a bit and added the following to ~/.pam_environment:TODAY=date +"%F"TODAYS=$(date +"%F")NOW=$(date +"%m-%d-%Y")None of these are working

@ScottGoodgame That's not the problem. It is not generally necessary to quote%, and although the reference you provided follows this style, it does not actually say one has to do so. Try some examples from that page without quotes (e.g.,date +%m-%d-%y). It works fine. In addition,TODAY= date +"%F"actually runsdate +"%F"withTODAYset to the empty string in its environment.
